Probably would healed properly once he gets enough rest. Also, as long Scaloni (or whoever the next DT) could manage his playing time properly, he'd still be more dangerous than 99% of players out there. We've seen what ADM could do in last few years under Scaloni despite constantly getting injured at crucial matches under previous managers. Half true, Messi is approaching 1100 games in his career and most players at his age dont play as many matches/minutes. Messi rarely ever gets subbed out in last 14 years or so. Zanetti was 36 when he won treble with Inter and also played well over 1000 games but he never rely on short burst acceleration. Messi needs that to be effective.
